Starting with 3.8rc1 I get a black screen when resuming after suspend. 
The kernel is alive because I can switch to VT1 and reboot with 
ctrl-alt-delete.

I bisected the problem down to this commit:

186ecad21: drm/nv50/disp: move remaining interrupt handling into core

Hardware is 8400M GS (10de:0427) in a Dell XPS M1330.

I see this in my kernel log after resume:

nouveau E[     PFB][0000:01:00.0] trapped read at 0x002001a020 on 
channel 0x00007b23 SEMAPHORE_BG/PFIFO_READ/00 reason: PAGE_NOT_PRESENT
